EM13c在受控主機上安裝agent，oracle用戶需要添加sudo權限

添加文件的寫權限
chmod u+w /etc/sudoers

編輯/etc/sudoers文件。也就是輸入命令

vi /etc/sudoers
root ALL=(ALL) ALL --這行下面增加一行
oracle ALL=(ALL) ALL

撤銷文件的寫權限

chmod u-w /etc/sudoers

測試

[root@dfmc-dbaasp-02 ~]# su - oracle
[oracle@dfmc-dbaasp-02 ~]$ sudo ls /root  --第一次需要輸入密碼

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

[sudo] password for oracle: 
anaconda-ks.cfg  install.log  install.log.syslog  zxq.sh  ??????  ?????????  ??????  ??????  ??????  ??????  ??????  ??????
[oracle@dfmc-dbaasp-02 ~]$ 
[oracle@dfmc-dbaasp-02 ~]$ 
[oracle@dfmc-dbaasp-02 ~]$ sudo ls /root  --第二次不需要輸入密碼
anaconda-ks.cfg  install.log  install.log.syslog  zxq.sh  ??????  ?????????  ??????  ??????  ??????  ??????  ??????  ??????
[oracle@dfmc-dbaasp-02 ~]$

在受控主機和EM13c主機上配置域名解析

[root@test-dbaas-01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.2.21.10   test-dbaas-01 test-dbaas-01.oracle.com
10.2.21.11   test-dbaas-02 test-dbaas-02.oracle.com
10.2.21.12   testdb1-vip
10.2.21.13   testdb2-vip
192.168.100.10 testdb1-priv1
192.168.200.10 testdb1-priv2
192.168.100.20 testdb2-priv1
192.168.200.20 testdb2-priv2
#添加如下
10.2.21.17 test-dbaasem-01 test-dbaasem-01.oracle.com

em13c主機

[root@dfmc-dbaasem-01 /]# cat /etc/hosts                                                                                                                              
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.2.21.17 test-dbaasem-01 test-dbaasem-01.oracle.com
#添加如下
10.2.21.10   test-dbaas-01 test-dbaas-01.oracle.com
10.2.21.11   test-dbaas-02 test-dbaas-02.oracle.com
